Pipeline shows disabled endpoints fix (#2881) (#3282)

# Description of Changes

Previously, the dropdown menu in the pipeline configuration displayed
all endpoints, including disabled ones, and allowed API calls to them.

Changes:

- Updated EndpointInterceptor to correctly parse request URIs and match
them to corresponding endpoint names in settings.yml, ensuring disabled
endpoints are blocked.

- Added a new API endpoint in SettingsController to expose the
endpointStatus map, allowing the frontend to check which endpoints are
disabled.

- Updated pipeline.js to use this new API and hide disabled endpoints
from the dropdown menu.

Tests:

- Created a new Docker Compose setup using a custom settings.yml where
all endpoints are disabled.

- Implemented a test script to run this setup, send API requests to
disabled endpoints, and verify they are correctly blocked.
